Formula of Sphere:
V = 4πr³/3 or V = 4/3πr³
SOLUTIONS:
1. 5m
V = 4 πr³/3
= 4 x 3.14 x 5³ / 3
= 4 x 3.14 x 5x5x5 / 3
= 4 x 3.14 x 125 / 3
= 12.56 x 125 / 3
= 1570 / 3
= 523.33 m³
2. 8dm
V = 4 πr³/3
= 4 x 3.14 x 8³ / 3
= 4 x 3.14 x 8x8x8 / 3
= 4 x 3.14 x 512 / 3
= 12.56 x 512 / 3
= 6430.72 / 3
= 2143.57 dm³
3. 10cm
V = 4 πr³/3
= 4 x 3.14 x 10³ / 3
= 4 x 3.14 x 10x10x10 / 3
= 4 x 3.14 x 1000 / 3
= 12.56 x 1000 / 3
= 12560 / 3
= 4186.67 cm³
4. 3f
V = 4 πr³/3
= 4 x 3.14 x 3³ / 3
= 4 x 3.14 x 3x3x3 / 3
= 4 x 3.14 x 27 / 3
= 12.56 x 27 / 3
= 339.12 / 3
= 113.04 f³
5. 4m
V = 4 πr³/3
= 4 x 3.14 x 4³ / 3
= 4 x 3.14 x 4x4x4 / 3
= 4 x 3.14 x 64 / 3
= 12.56 x 64 / 3
= 803.84 / 3
= 267.95 m³
